Definition/Description

An assemblage of mangrove trees which are mostly low trees noted for a copious development of interlacing adventitious roots above the ground and which contains one or more of the following species: Black mangrove, red mangrove, white mangrove, and buttonwood. Mangrove stands provide significant flood protection in some coastal areas by protecting landward areas from wave impacts. Human alteration of mangrove stands within V Zones is prohibited unless it can be demonstrated that such alteration will not increase potential flood damage.
